Opportunity Information: Apply for DE FOA 0003399
The Energy Storage Pilot Demonstrations opportunity (Funding Opportunity Number DE FOA 0003399) is a U.S. Department of Energy discretionary funding program that will support pilot-scale demonstrations of energy storage technologies. Awards will be made through cooperative agreements, which typically means DOE expects to be meaningfully involved during the project period (for example, through technical oversight, milestone reviews, and coordination on data and reporting) rather than issuing a hands-off grant. The opportunity sits within the Energy funding activity category (CFDA 81.255) and is administered by DOE Headquarters.
The core purpose of the program is to move energy storage solutions beyond lab and small prototype stages and into real-world pilot demonstrations where they can be tested under practical operating conditions. The emphasis is specifically on stationary storage applications, meaning systems intended for grid or facility-based use rather than mobile or transportation uses. A central technical priority is long-duration storage with a target of around 10 hours of discharge, which aligns with grid needs such as evening peak support, renewable energy shifting, resilience during outages, and reducing reliance on peaker plants. Another defining feature is the focus on non-lithium technologies, signaling DOE interest in diversifying beyond conventional lithium-ion systems due to concerns such as supply chain constraints, cost volatility, safety considerations, and the need for solutions better suited for long-duration duty cycles.
The program lays out three main outcomes it wants to achieve through these demonstrations. First, it aims to advance a diverse set of non-lithium storage technologies toward commercial viability and eventual utility-scale deployment. In practice, this means projects should be designed to prove not only that the technology works, but that it can be manufactured, deployed, operated, maintained, and scaled in a way that utilities and other stationary-storage buyers could realistically adopt. Second, the program wants to produce high-quality operational datasets and techno-economic models. That signals a strong preference for rigorous measurement, monitoring, and reporting of performance (such as efficiency, degradation, availability, response characteristics, and operational constraints), paired with credible cost and economic analyses that can be used to evaluate pathways to competitive levelized cost of storage and other relevant financial metrics. Third, DOE is explicitly trying to build confidence among investors, utilities, and end users by validating real-world performance and adoptability. This is essentially a market-enabling goal: the pilots should reduce perceived technology risk, clarify operational requirements, and provide evidence that the systems can meet grid and customer needs reliably.
Eligibility is listed as unrestricted, suggesting a wide range of applicants may be able to apply (for example, private companies, utilities, developers, universities, national-lab partners, and other organizations), although specific teaming or cost-share expectations would normally be detailed in the full funding announcement. The posted award ceiling is $20,000,000, indicating individual awards could be substantial, consistent with the costs of building and operating pilot-scale hardware, interconnecting to facilities or the grid, and conducting extended operational testing. The original closing date is February 13, 2025, and the opportunity was created on September 6, 2024. The listing shows “ExpectedAwards: 0,” which often reflects that the number of awards was not specified in the source entry rather than indicating no awards will be made.
Overall, this opportunity is aimed at bridging the gap between promising non-lithium, long-duration stationary storage concepts and bankable, utility-relevant solutions by funding real pilot deployments that generate trustworthy performance data and economics. The program is structured to encourage demonstrations that are credible to the market, measurable in a way that supports strong modeling and comparison, and practical enough to inform the next step toward commercial and utility-scale adoption.Apply for DE FOA 0003399
